(CNN) -- US airline passengers who figured face mask enforcements had more bark than bite could end up getting bit later this week. If you refuse to wear a face mask starting June 18, you could find yourself on a restricted travel list. If you don't have a face covering, United flight attendants will offer you one. But a major union representing flight attendants said last week the current approach was not working. United Airlines began doing that last week.
